I was mistaken. It was a weber chain that broke

Lotsa roller chains will actually stretch faster than a stock single chain so research can be useful if in doubt of brand.  I think RollMaster has good rep and offers a pre-stretched chain in at least some versions.

An old trick that seemed to help was to submerge the new chain in oil that was heated to about 200 degrees for about an hour.  A moly additive in the oil was suggested.  This seems to have increased the life of the chain substantially.  this probably only works on chevies so....:)

A lot of broken parts does not make you a racer; it makes you a slow learner.

It broke on Keith's car but we don't know if it was the chain's fault, or something else for sure.  Car has run okay since the engine was rebuilt

Your right about them stretching.  When I was running that 429, I would change the timing set every spring. 
I was curious if these sets would stretch as quickly since we are turning two less sets of springs

According to Isky..
".. An excessively stretched chain can retard cam timing, as much as four cam degrees, because of the slack in the links. Also, even though most of the valve timing figures in this catalog are listed at split overlap, most of our camshafts are ground from one to two cam degrees advanced to allow for eventual stretch in the timing chain..."

Just means that it will makes more power up top later on down the road. ;)

IT was my chain that had broke, it was the one from Weber and I never found the reason that the chain broke other than it just broke. I did go with the Roll Master set on the rebuild BUT I had to ream the holes on the cam gear to get it to line up.
